Answer:

$30$

Step-by-step explanation:

The best choice for a common denominator will always be the least common multiple of the two denominators. In this case, the least common multiple of 5 and 6 is 30, so $\boxed{30}$ is the best choice.

<em>The LCM of two numbers is the lowest integer that divides them both evenly</em>

Evaluate limit:<br> lim x approaches 0 e^(5x)-1-5x/x^2

rosijanka [135]

Lim as x approches 0 of (e^(5x) - 1 - 5x)/x^2 = lim as x approaches 0 of (5e^(5x) - 5)/2x = lim as x approaches 0 of 25e^(5x)/2 = 25/2 = 12.5

Which expression uses the associative property to make it easier to evalute?

mixas84 [53]

Answer:

The correct option is (c).

Step-by-step explanation:

The given expression is :

$14(\dfrac{3}{2}\times \dfrac{1}{4})$

We need to use the associative property to make it easier.

The associative property for multiplication is as follows :

$A\times (B\times C)=(A\times B)\times C$

We have,

$A=14, B=\dfrac{3}{2}\ and\ C=\dfrac{1}{4}$

$14(\dfrac{3}{2}\times \dfrac{1}{4})=(14\times \dfrac{3}{2})\times \dfrac{1}{4}$

Hence, the correct option is (c).
